Interpretation and clinical management of patients with Fixed myocardial perfusion defects, https://doi.org/10.1007/s12350-020-02492-8. This may be achieved with improvement in coincidence time resolution (lower than 100 ps) through new PET detector designs, and some day even crossing the 10 ps, which will increase the performance of time-of-flight PET dramatically, resulting in a better signal-to-noise ratio of the activity measurement (e.g., F-18 Flurpiridaz), improving the reconstruction process and rendering quantifying the endocardial-to-epicardial distribution of myocardial blood flow achievable and attainable.

I was diagnosed with ejection fraction rate 75%, very small reversible apical defect with myocardium at risk. Stress is directly linked to the six leading causes of death. Severe fixed defect most likely represents scarring or fibrosis from prior MI, but a mild or moderate fixed defect may indicate hibernating myocardium or prior nontransmural MI. Doctors use SPECT to diagnose coronary artery disease and find out if a heart attack has occurred.

To further split the transmural myocardial blood flow from an already small left ventricular myocardium region or segment into subendocardial and subepicardial components is a daunting task. is test neg? Subendocardial and subepicardial myocardial blood flow has been previously calculated for each of the three coronary artery vascular territories.18 However, dividing the absolute myocardial perfusion parameter from a global index, to the 3 individual vascular territories, and further into 5 myocardial regions or 17 segments, indubitably increases the error of the measurement. It is mainly due to the blood perfusion insufficiency of the myocardium. This reversible defect shows artery blockage and results in heart failure if not treated timely. When both viable myocardium and scarred myocardium are present, the defect may be characterized as mild-moderate fixed, which connotes non-transmural infarction, and can also be seen after percutaneous coronary intervention in the setting of acute coronary syndrome (Table 1 ).
